Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh
In the Name of Allah, the All-Merciful, the Mercy-Giving
All praise is due to Allah. Peace and blessings be upon His Messenger Muhammad.
In this fatwa:
Answering your question, Sheikh Kifah Mustapha, the Imam and Director of The Prayer Center of Orland Park and representative for Dar El Fatwa of Lebanon in the US, states:
Scholars agreed that it is better, if the imam happens to be handicapped, to assign someone else instead.
If the imam prayed sitting down, it is still accepted. There is a hadith in which the Prophet (peace and blessings be upon him) said, “If the Imam prays sitting, you should all pray sitting.” (Al-Bukhari and Muslim)
But scholars said it is better if they sit like him. But if they stand, it is accepted.
I lean to the idea that the imam should allow someone else to lead.
Almighty Allah knows best.
